摘要
为研究二元矢量喷管的内流特性,掌握宽高比、收敛角、扩张角等关键参数对二元矢量喷管气动性能的影响规律,本文通过数值模拟,针对圆转方段出口矩形高度、圆转方段长度、收敛角、扩张角、扩张段长度、喉道宽高比和喉部倒圆半径对喷管气动性能的影响分别进行了研究,得到了上述各个参数对二元矢量喷管的推力系数、流量系数和总压恢复系数的影响规律,并根据研究结果,对工程应用的二元矢量喷管方案设计提出了建议。
In order to study the internal flow characteristics and master the effects of the key parameters such as the ratio of width and height,convergence angle,divergence angle on the aerodynamic performance of two-dimensional vectored nozzle.The effects on nozzle's performance of the key parameters such as the height of the circular-to-rectangular transition duct,the length of the circular-to-rectangular transition duct,convergence angle,divergence angle,the length of the divergence,the ratio of width and height of throat and throat radius,are calculated and analyzed through numerical simulation.The influence law on the nozzle's thrust coefficient,flow coefficient and total pressure recovery coefficient are obtained.On the basis of the research results,the suggestions are made on the design of two-dimensional vectored nozzle used for engineering.
